Operation/Installation Manual

6.When replacing the amplifier's fuse, always use one having the same amperage rating. Substituting a higher rated fuse or a slow-blow type can result in serious damage to the amplifier.

7.When creating passage holes for power cables, RCA's cords, and speaker wires, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short circuit.

8.Extra cable can cause signal loss and act as an "antenna" for noise. Use only high-quality RCA cords that are no longer than necessary.

9.In multiple amplifier systems, it is recommended to use a relay on the remote turn-on lead of the radio.
